1、It is found that there exist odd harmonics, even harmonics and semi-integer harmonics due to the coherent interaction between two colors.
2、It proves that it is feasible to apply the wavelet transformation to the detection of non-integer harmonics, thus, an effective means is provided for accurate detection of harmonics.
3、The wavelet function is such a function which possesses good localization characteristics, so theoretically it can be applied to the detection of non-integer harmonics.
